Answer:
<h2>Equilibrium</h2>
Explanation:
The pendulum is at rest ( or balance due to the equal action of opposing forces).
Answer:
Ep = 117600 J
Explanation:
Data:
- Mass (m) = 600 kg
- Height (h) = 20 m
- Gravity (g) = 9.8 m/s²
- Potential Energy (Ep) = ?
Use formula:
Replace:
- Ep = 600 kg * 9.8 m/s² * 20 m
Multiply operations, and units:
What is the potential energy?
The potential energy is <u>117600 Joules.</u>
5.91(approx) seconds just divide velocity by acceleration
In a surface wave (like water) the water goes up and down, but the wave travels across (parallel to) the surface.
